Review: Keeps it HOT! - I haven't had the opportunity to keep anything cold in this Thermos yet, but I can say it definitely keeps my tea hot 24 hrs. I pre-heat it for about 10-20 mins before filling with hot tea, and it keeps it steaming hot 24 hours. It could possibly keep it hot longer, but I usually drink the last cup right at 24 hours after filling. ## Features - Thermos vacuum insulation technology for maximum temperature retention, keeps hot for 24 hours and cold for 24 hours - Stainless steel interior and exterior featuring protective silicone rings for high durability - Cool to the touch with hot liquids, sweat-proof with cold - Two part stopper to smooth the flow of liquids - BPA Free.5 year guarantee ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013YMS8RM | | Additional Features | Durability,Lightweight | | Age Range (Description) | Adult | | Age Range Description | Adult | | Base Diameter | 8.2 centimeters | | Best Sellers Rank | #371,492 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #2,814 in Insulated Bottles | | Brand | THERMOS | | Brand Name | THERMOS | | Cap Type | Screw Cap | | Capacity | 900 ml | | Color | Gray | | Customer Reviews | 4.7 out of 5 stars 2,220 Reviews | | EU Spare Part Availability Duration | 5 years | | Global Trade Identification Number | 05010576041104 | | Included Components | Lid | | Item Dimensions W x H | 3.15"W x 11.81"H | | Item Type Name | Ultimate MKII Series Flask 900ml | | Manufacturer | Thermos | | Material Type | Silicone Stainless Steel | | Model Name | FFX900 | | Number of Items | 1 | | Pattern | Solid | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Water | | Special Feature | Durability,Lightweight | | Theme | Solid | | Unit Count | 1 Count | ## Product Details - **Brand:** THERMOS - **Capacity:** 900 ml - **Color:** Gray - **Recommended Uses For Product:** Water - **Special Feature:** Durability,Lightweight ## Images ![Thermos Charcoal Ultimate Drinks Flask (900ml) 24h Hot | 24h Cold - Image 1](https://m.media-amazon.com/images/I/618DdFWdwpL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: What country is it made in?** A: Made in malaysia ## Customer Reviews ### ⭐⭐⭐⭐⭐ Overseas shipping slow. *by G***K on November 12, 2025* Great product.
